Buying an Idaho City, ID Rental: The $16,176 Year for STR hosts

Idaho City, Idaho sits in the Boise National Forest along Highway 21, a former gold-rush county seat with a Census population of 466 and a short-term rental market that is genuinely small: the current AirROI sample counts 41 active listings.

That sample publishes a typical year of $16,176, with ADR near $199, occupancy near 27.6 percent, RevPAR near $56, an average stay of 2.3 nights, and only 7.3 percent of listings professionally managed - numbers that describe a real but modest cabin-town market, not a Boise suburb.

This is not legal or financial advice. It is a practical underwriting note for a buyer or lender looking at an Idaho City parcel: what this 41-listing sample actually supports, and why Garden Valley's $27,102 and Boise's $25,127 belong on their own separate lines rather than blended into this town's own number. This is not legal advice.

The Published Year: $16,176 on 41 Listings

The AirROI extract for Idaho City publishes a typical year of $16,176 across 41 active listings, with ADR near $199 and occupancy near 27.6 percent - the figures a buyer, lender, or DSCR underwriter should treat as this specific town's floor.

RevPAR (revenue per available night) comes out near $56 on this sample, and the average booked stay runs 2.3 nights, which points to a mostly weekend and short-trip market built around forest recreation rather than long stays or corporate travel.

With only 41 listings in the sample, any single strong or weak property carries real weight in the average, so a buyer should ask for the listing-level extract, not just the headline typical year, before treating $16,176 as a promise for a specific parcel.

Professional management sits at just 7.3 percent of this sample, which tells a buyer that most Idaho City hosts are self-managed - useful context for a buyer weighing whether to hire help or run the property directly.

Keep This Separate From a Boise Year

Boise City itself publishes a very different profile: roughly $25,127 in typical annual revenue, ADR near $195, and occupancy near 47.8 percent - a market with far deeper demand and a very different guest mix than a forest town of 466 residents.

Idaho City's occupancy sits at roughly half of Boise's, which is the core reason a broker memo cannot simply cite 'Boise-area STR performance' and apply it to an Idaho City parcel: the two markets share a metro name but not a competitive set.

A buyer comparing the two should hold Idaho City's $16,176 and Boise's $25,127 on separate labeled lines in any underwriting file, the same way a lender would never blend two different zip codes' comps into one appraisal.

The failure mode worth naming directly: do not underwrite an Idaho City closing on a Boise year. The gap between $16,176 and $25,127 is not rounding error - it changes the debt-service math entirely.

Garden Valley Is a Different market, Too

Garden Valley, another small Boise National Forest gateway town, publishes its own typical year near $27,102 - higher than both Idaho City and Boise proper, likely reflecting a different mix of larger cabin-style properties and different seasonal demand patterns.

That $27,102 figure belongs to Garden Valley's own listing sample, not to Idaho City's. A buyer or agent who cites Garden Valley numbers while marketing an Idaho City parcel is misrepresenting the deal to a lender or a future buyer.

The practical rule for any small mountain-town STR file: pull the town-specific extract, confirm the listing count behind it, and never let a regional average or a neighboring town's stronger number stand in for the parcel's own comps.

If a broker memo arrives with a blended Boise-Garden Valley-Idaho City figure, ask for the underlying town-by-town breakdown before treating the headline number as real.

Census 466 Travels With the Deed

Idaho City's Census population of 466 is a small-town fact that matters for underwriting: local labor for cleaning and maintenance, code-enforcement capacity, and the depth of the local rental market are all shaped by a town this size.

A buyer should confirm who actually cleans and turns the property between stays in a town this small, since the professionally-managed share sitting at just 7.3 percent suggests thin local vendor capacity compared to a bigger market.

Population size also shapes the regulatory conversation: a town of 466 people is more likely to have informal or evolving short-term rental rules than a city the size of Boise, which is one more reason to confirm the current rule set directly rather than assume it.

None of this replaces a site visit and a conversation with the county assessor's office - but it does mean a buyer should not treat Idaho City as a smaller version of Boise with the same infrastructure.

HB 583 Is Diligence, Not Occupancy

Idaho's HB 583 sits in the diligence file for any short-term rental purchase in the state - it is a piece of state-level regulatory context a buyer should confirm with counsel, not a number that changes the AirROI occupancy or ADR figures above.

A buyer's checklist should keep the regulatory question (is this specific parcel and use legal under current state and local rules) separate from the performance question (what does this parcel's local market actually earn) - conflating the two is a common underwriting mistake.

This post does not offer legal interpretation of HB 583's requirements for a specific address; a buyer should confirm current requirements directly with the relevant county or state office before closing.

The point for this file is simple: regulatory diligence and revenue diligence are two separate line items, and neither one should be skipped because the other looks favorable.

Two Halls Travel With the Parcel

An Idaho City short-term rental purchase likely touches more than one local desk - potentially both a county-level office and a more local permitting or tax-collection contact - and a buyer should confirm both before assuming the deal is clean.

"Two halls travel with the parcel" is a useful shorthand for buyers: do not assume a single phone call or a single online search resolves every registration, tax, or permit requirement tied to a specific Idaho City address.

A buyer who confirms both desks before closing avoids the common post-closing surprise of discovering a second registration requirement or a tax-collection obligation that was not disclosed in the listing packet.

This confirmation step costs an afternoon of phone calls and saves months of after-the-fact compliance cleanup - a worthwhile trade for any DSCR file.

What a Buyer Packet Should Actually Carry

A clean Idaho City buyer packet should carry: the town-specific AirROI figures ($16,176 typical year, $199 ADR, 27.6 percent occupancy, 41-listing sample size), not a Boise or Garden Valley substitute.

It should also carry confirmation of both local registration desks, a direct answer on HB 583 diligence from qualified counsel, and an honest accounting of cleaning and management costs given the thin 7.3 percent professionally-managed share in this market.

A lender reviewing a DSCR file on this parcel will want the same things: town-specific revenue, confirmed legal operating status, and a management cost line that reflects the local vendor reality rather than a national average.

Before you bid on an Idaho City parcel, send the actual listing address and packet to a second set of eyes. We will not mint a corridor-wide revenue figure to make a deal look better than the 41-listing sample supports.

None of the figures above substitute for your own site visit, your own conversation with local officials, or your own lender's underwriting standards - they are a starting point for asking better questions, not a closing document.

Frequently Asked Questions

What is Idaho City's actual typical short-term rental year?

The AirROI sample publishes a typical year of $16,176 across 41 active listings, with ADR near $199 and occupancy near 27.6 percent. That is the town-specific floor a buyer or lender should underwrite from, not a Boise or Garden Valley substitute. Given the small 41-listing sample, ask for the listing-level extract before treating the headline figure as guaranteed for a specific parcel.

Why can't a buyer use Boise's STR numbers for an Idaho City parcel?

Boise City publishes roughly $25,127 in typical annual revenue with occupancy near 47.8 percent, almost double Idaho City's 27.6 percent. The two markets share a metro area but not a competitive set, since Idaho City is a small forest gateway town of 466 residents rather than a state capital. Blending the two numbers into one underwriting file materially overstates what an Idaho City property will actually earn.

How does Garden Valley's number relate to Idaho City's?

Garden Valley, another nearby Boise National Forest town, publishes its own typical year near $27,102 - higher than Idaho City's $16,176. That figure belongs to Garden Valley's own listing sample and should never be cited as evidence for an Idaho City parcel's earning potential. Any memo that blends the two towns into one regional average is misrepresenting the deal.

What does Idaho City's Census population of 466 mean for a buyer?

A town this small has thin local vendor capacity for cleaning and maintenance, which likely explains why only 7.3 percent of the AirROI sample is professionally managed. It also means local regulatory infrastructure may be less developed than in a larger city, so a buyer should confirm current rules directly rather than assume they mirror a bigger market. Population size is a useful diligence flag, not a revenue input.

Does Idaho's HB 583 affect the AirROI revenue figures?

No - HB 583 is a state-level regulatory diligence item, separate from the performance numbers reported by AirROI. A buyer should confirm HB 583's current requirements for the specific parcel with qualified counsel or the relevant state office, and treat that as its own checklist item. Conflating regulatory diligence with revenue diligence is a common and avoidable underwriting mistake.

What are the two local desks a buyer should confirm before closing?

An Idaho City short-term rental purchase likely touches more than one local office - potentially a county-level desk and a more local permitting or tax-collection contact - and both should be confirmed before closing. Skipping this step is how buyers discover a second registration requirement after the deal is already done. A single afternoon of phone calls resolves this cleanly.

What should a DSCR lender want to see in an Idaho City file?

A lender should expect town-specific revenue figures (the $16,176 typical year on 41 listings), confirmed legal operating status for the exact parcel, and a realistic management-cost line given that only 7.3 percent of the local market is professionally managed. Anything that substitutes a Boise or Garden Valley number for Idaho City's own figures should be flagged and corrected before underwriting proceeds.

Why does the average stay length of 2.3 nights matter for underwriting?

A 2.3-night average stay signals a weekend and short-trip market built around forest recreation rather than extended or corporate stays, which affects both cleaning-turnover costs and realistic occupancy ceilings. A buyer projecting long-stay or remote-worker demand onto this market would be building a pro forma the local guest pattern does not support. This figure should shape the cleaning and turnover cost line in any packet.
